Subject: [PATCH] i2c: mux: gpio: Add missing fwnode_handle_put()
In i2c_mux_gpio_probe_fw(), we should add fwnode_handle_put()
when break out of the iteration device_for_each_child_node()
as it will automatically increase and decrease the refcounter.
Fixes: 98b2b712bc85 ("i2c: i2c-mux-gpio: Enable this driver in ACPI land")
